When it comes to engine cooling, whether you're talking coolant fans or an oil, tranny or power steering cooler, usually more cooling is better. The exact CFM cooling requirement for a V8 engine will vary somewhat among makers, the other equipment installed and the intended use - racing versus towing versus rock crawling, for example. Check with your engine manufacturer.

These fans can be sorted based on size in order to fit your available mounting location, or by CFM air-moving capacity, which goes as high as 4000-CFM. These high-output dual fan assemblies will often include a shroud to better route air through the radiator.

For example, the Derale Dual High-Output, Electric Radiator Fan-and-Shroud Assembly # D16927 measures 26 Wide x 18 tall x 3-3/4 deep. Each of its two 265-watt fans draws 24.8 amps maximum.
